FIG. 4 is a side view showing the case where the headset 1 is mounted on the head H, and FIG. 5 is a front view. FIG. 6 is a side view showing a case where the headset 1 is not attached to the head H.

  As shown in FIGS. 1 to 3, the headset 1 includes a communication unit 16, a pair of speakers 11, a pair of detection units 12, a vibration generation unit 13, a control unit 15, and a support unit 14. I have. The support portion 14 has a U-shape, and has both end portions 14b facing each other and a central portion 14a located between the both end portions 14b. The central portion 14a of the support portion 14 refers to a portion near the center when the support portion 14 is viewed along a U-shape. The pair of speakers 11 are respectively supported by both end portions 14b so as to face each other. A pair of detection part 12 is each supported by the both ends 14b so that it may mutually oppose. The communication unit 16, the vibration generation unit 13, and the control unit 15 are supported by the central portion 14 a of the support unit 14. A microphone 17 is attached to one end portion 14 b of the support portion 14 via a microphone attachment portion 18. In addition, the speaker 11 and the detection part 12 are not restricted to a pair, You may be provided only in one edge part 14b.

  The communication unit 16 communicates with an external device owned by a communication partner by radio. The communication unit 16 includes, for example, an antenna and a wireless module. As the communication method, for example, a frequency band of 422 MHz band or 440 MHz band is used. In addition, when communicating via a repeater (not shown) that relays communication with an external device, the communication method of the communication unit 16 is, for example, a 2.4 GHz band frequency band such as Bluetooth (registered trademark). Is used. The signal received by the communication unit 16 is amplified by the control unit 15.

  The speaker 11 outputs the signal received by the communication unit 16 and amplified by the control unit 15 as sound. As shown in FIGS. 4 and 5, the speaker 11 is provided on the support portion 14 so as to contact the skin H <b> 1 positioned in front of the ear E when the headset 1 is attached to the head H. Specifically, the speaker 11 is a bone conduction speaker having a metal diaphragm. The vibration by the speaker 11 is mainly transmitted from the skin H1 in front of the ear to the auditory nerve via the skull of the human body M. The user of the headset 1 can recognize the communication partner's voice by bone conduction.

  The detection unit 12 detects whether or not the headset 1 is worn on the user's head H. As the detection unit 12, for example, a pressure sensor, a temperature sensor, a capacitive contact sensor, an optical sensor, a mechanical switch, or the like is used. The detection unit 12 is provided so as to detect that it is attached to the head H in contact with the human body M only when the headset 1 is attached to the head H. Specifically, the detection unit 12 is provided at the end 14 b of the support unit 14 and below the speaker 11. Thus, as shown in FIGS. 4 and 5, when the headset 1 is worn, the detection unit 12 contacts the skin (human body M) located under the skin H <b> 1 in front of the ear and touches the head H. Detects wearing. In addition, as shown in FIG. 6, when the headset 1 is put on the neck (when the headset 1 is not attached to the head H), the headset 1 is in contact with the human body M. 12 does not contact the human body M and does not detect that it is attached to the head H.

  The electrical signal detected by the detection unit 12 is sent to the control unit 15. The control unit 15 converts the signal detected by the detection unit 12 into a voltage, and determines whether or not the detection unit 12 detects the human body M (whether or not it is in contact with the human body M) based on the magnitude of the voltage. to decide.

  The support part 14 is mainly composed of a resin material. Inside the support portion 14, aggregates such as wires and wiring (wiring for connecting the control unit 15, the communication unit 16, the speaker 11, the detection unit 12, the vibration generation unit 13, and the like) are provided. The support portion 14 has a U-shape, and has a structure in which the central portion 14a of the support portion 14 is brought into contact with the back of the neck and can be hung on the neck. Both end portions 14b of the support portion 14 have a columnar shape extending vertically. The pair of speakers 11 are provided above the both end portions 14b, and the pair of detection portions 12 are provided below the both end portions 14b. Yes. The central portion 14a has a space inside, and the communication unit 16, the vibration generating unit 13, and the control unit 15 are provided in the space. The headset 1 has a substantially bilaterally symmetric (line symmetric) shape.

  Moreover, the support part 14 has elasticity, and parts other than the center part 14a of the support part 14 are easy to bend. Specifically, the support portion 14 has a structure in which a portion other than the central portion 14a can be bent to change the facing distance between both end portions 14b. When the headset 1 is mounted on the head H, the elastic force of the support portion 14 is adjusted so that the speaker 11 does not move away from the skin H1 in front of the ear and does not press the skin H1 too much. .

  The support portion 14 is formed so as to bypass the lower side of the ear E from the both end portions 14b to the central portion 14a located on the rear side of the head H when the headset 1 is worn. By detouring the lower side of the ear E, it is easy to wear glasses, and by forming it so as to extend to the central part 14a located on the back side of the head H, it is easy to wear a helmet or a hat. The central portion 14a and the back of the head are spaced apart from each other without being in contact with each other.

  The vibration generating unit 13 applies vibration to the human body M by generating vibration. In order to suppress this vibration from being confused with the sound output from the speaker 11, vibration outside the audible region is used. The frequency of vibration may be higher or lower than the audible range. As the vibration generating unit 13, for example, a motor having an eccentric weight attached to a rotating shaft, a piezoelectric element, or the like is used.

  As shown in FIG. 6, the vibration generating unit 13 is provided on the support unit 14 so as to be close to the back of the neck when the headset 1 is removed from the head H and the support unit 14 is hung on the neck. When the vibration generating unit 13 is vibrated in the state of being close to the neck, the vibration is directly transmitted to the human body M without passing through the air, and the user of the headset 1 is easily aware of the vibration.

  The microphone 17 inputs sound emitted from the human body M (user). The microphone 17 is disposed so that the microphone 17 is positioned in front of the user's mouth when the headset 1 is used. The sound input from the microphone 17 is converted into an electrical signal by the control unit 15 and sent to the communication unit 16.

  The control unit 15 includes a central processing unit (CPU), a random access memory (RAM), and a read only memory (ROM). The control unit 15 amplifies the signal received by the communication unit 16 and outputs the amplified signal to the speaker 11. Further, the control unit 15 converts the sound input from the microphone 17 into an electrical signal and transmits the electrical signal to the external device using the communication unit 16.

  The control unit 15 of the headset 1 in this embodiment determines whether or not the communication unit 16 is in an incoming state, the communication unit 16 is in an incoming state, and the headset 1 is attached to the head H. When the detection unit 12 detects that the vibration has not occurred, the vibration generation unit 13 is vibrated. This vibration notifies the user that the headset 1 is not worn, and prompts the user to wear the headset 1. Thereby, the start of a telephone call is performed smoothly.

  Here, the shape of the speaker 11 and the positional relationship between the speaker 11 and the detection unit 12 will be further described. FIG. 7 is an enlarged perspective view of the end portion 14 b of the headset 1.

  As shown in FIG. 7, the speaker 11 includes a cylindrical columnar part 11 b and a protruding part 11 a that protrudes from the cylindrical part 11 b toward the center part 14 a of the support part 14. The protruding portion 11 a protrudes toward the central portion 14 a of the support portion 14 with respect to the detection portion 12. In other words, the detection part 12 is located on the end part 14b side (on the opposite side to the central part 14a) from the protruding end of the protruding part 11a.

  Since a part of the speaker 11 protrudes toward the central portion 14a side from the detection unit 12, the headset 1 is removed from the head H and the support unit 14 is put on the neck as shown in FIG. When moved back and forth, the speaker 11 hits the neck first, and the detection unit 12 is less likely to hit the neck. With this structure, even when the vibration generating unit 13 is vibrated when the headset 1 is removed from the head H, the detection unit 12 is prevented from detecting the neck or the like. Therefore, when the headset 1 is removed from the head H, it can suppress giving the misinformation that the headset 1 is mounted | worn. In addition, it is good also as a structure which enlarges the diameter of the cylindrical part 11b of the speaker 11, and protrudes a part of speaker 11 to the center part 14a side rather than the detection part 12. FIG.

[1-2. Headset operation]
The operation of the headset 1 configured as described above before the call starts will be described. FIG. 8 is a flowchart showing an operation of the headset 1 before starting a call.

  First, the control unit 15 determines whether or not the communication unit 16 is in an incoming state when starting a call (S11). Specifically, it is determined whether or not the communication unit 16 has received a call signal from an external device. If it is not in the incoming state (No in S11), it does not proceed to the next step and waits.

  If the communication unit 16 is in an incoming state (Yes in S11), the process proceeds to the next step, and the control unit 15 determines whether or not the detection unit 12 has detected the human body M (S12). When the detection unit 12 detects the human body M (Yes in S12), it is considered that the headset 1 is attached to the head H, and a call is started (S14).

  On the other hand, when the detection unit 12 does not detect the human body M (No in S12), it is assumed that the headset 1 is not worn on the head H, and the vibration generation unit 13 is vibrated (S13). This vibration prompts the user to wear the headset 1. The user who notices the vibration wears the headset 1. With this wearing, the detection unit 12 detects the human body M (Yes in S12), and a call is started (S14).

  In addition, the control part 15 vibrates the vibration generation part 13 or emits a notification sound from the speaker 11 when receiving an incoming call with the headset 1 attached (Yes in Step S11). The user may be notified that there is an incoming call from the other party. Further, in the case of No in step S12, the control unit 15 may notify the communication partner using the communication unit 16 that the user is not wearing the headset 1.

  Thereby, when it is not desired to attach the headset 1 to the head H, for example, the U-shaped support portion 14 can be hung on the neck and removed from the head H. Even if it exists, by vibrating the vibration generation part 13, a vibration can be given through the neck and it can be noticed that there exists an incoming call. Therefore, even if the user does not wear the headset 1 on the head H, it can be noticed that there is an incoming call due to vibration, and the call can be started smoothly.

  In the present embodiment, the speaker 11 may be provided at the end portion 14 b of the support portion 14, and a part of the speaker 11 may protrude toward the center portion 14 a side of the support portion 14 relative to the detection portion 12.

  According to this, for example, when the headset 1 is removed from the head H, and the support portion 14 is moved back and forth with the support portion 14 of the headset 1 being put on the neck, the speaker 11 hits the neck first and is detected. The part 12 is difficult to hit the neck. Therefore, when the headset 1 is removed from the head H, even if the vibration generating unit 13 is vibrated, the detection unit 12 is suppressed from detecting the neck or the like. Thereby, when the headset 1 is removed from the head H, it can suppress giving the misinformation that the headset 1 is mounted | worn.
